[0050] Please refer to Figure 1 This embodiment provides an electrical device 020, which may refer to a wall socket; of course, in other embodiments, the electrical device 020 may also refer to a wall switch, etc., which is not specifically limited here.

[0051] The electrical device 020 includes a base box 500 , a fixing frame assembly 510 and an electrical body 520 . The base box 500 is used to be mounted on a wall or other installation location; the electrical body 520 is mounted on the fixing frame assembly 510 , and the fixing frame assembly 510 is connected to the base box 500 .

[0052] It should be understood that in other embodiments, the electrical device 020 may not include the base box 500, and the fixing frame assembly 510 may be directly mounted on an installation location such as a wall, which is not specifically limited here.

[0053] It should be noted that the electrical device 020 in this embodiment is a wall socket, and the electrical body 520 may refer to the socket body; in the embodiment where the electrical device 020 is a wall switch, the electrical body 520 may refer to the switch body, which will not be listed one by one here.

[0054] Further, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The fixing frame assembly 510 includes a fixing frame 511, a fastening structure 010 and a fastener 530. The electrical appliance body 520 is assembled on the fixing frame 511. The fastening structure 010 is arranged on the fixing frame 511. The fastener 530 is arranged on the fastening structure 010 and connected to the bottom box 500 so that the fixing frame 511 is assembled on the bottom box through the fastener 530 and the fastening structure 010. Figure 2 and Figure 5The fastening structure 010 includes a first fixing member 100 and a second fixing member 200. The first fixing member 100 is provided with a clamping wall 111, the second fixing member 200 is provided with a second fastening hole 210, and includes a supporting portion 240. The fastener 530 is provided in the second fastening hole 210 and can be supported by the clamping wall 111 and the supporting portion 240. Specifically, when the fastener 530 is passed through the second fastening hole 210, the first fixing member 100 and the second fixing member 200 can approach each other under the extrusion action of the fastener 530, and one of the first fixing member 100 and the second fixing member 200 can move relative to the other along a set direction a so that the fastener 530 is clamped between the clamping wall 111 and the supporting portion 240, and the set direction a is distributed at an angle to the axial direction of the fastener 530.

[0055] The abutting portion 240 of the second fixing member 200 in the above “the second fixing member 200 is provided with a second fastening hole 210 and includes a holding portion 240” can be a separate component independent of the second fastening hole 210, or can be the hole wall of the second fastening hole 210; that is, in some embodiments, the abutting portion 240 is the hole wall of the second fastening hole 210, and the fastener 530 provided in the second fastening hole 210 is only clamped between the clamping wall 111 and the second fastening hole 210. In other embodiments, the abutting portion 240 is an independent component, and the fastener 530 provided in the second fastening hole 210 can be clamped by the clamping wall 111 of the first fixing member 100 and the abutting portion 240 of the independent component of the second fixing member 200, or the fastener 530 provided in the second fastening hole 210 can be simultaneously abutted by the clamping wall 111, the hole wall of the second fastening hole 210, and the abutting portion 240 of the independent component of the second fixing member 200. It should be understood that in the embodiment in which the fastener 530 can be simultaneously clamped by the clamping wall 111, the hole wall of the second fastening hole 210, and the abutting portion 240 of the independent component of the second fixing member 200, the hole wall of the second fastening hole 210 can also be understood as another abutting portion 240, and the fastener 530 is equivalent to being clamped by the clamping wall 111 and the two abutting portions 240 at the same time.

[0056] By clamping the fastener 530 by the clamping wall 111 and the abutting portion 240, the friction coefficient of the fastener 530 can be increased, thereby reducing the axial force provided by the fastener 530. The axial force provided by the fastener 530 is F, where F = (T × 1000) / (K × d), where T is the tightening torque (unit: N·m), d is the diameter of the fastener 530 (unit: mm), and K is the torque coefficient. When the fastener 530 is clamped by the clamping wall 111 and the abutting portion 240, the friction coefficient increases, and the K value increases. According to the above formula, when the diameter d of the fastener 530 and the tightening torque T are constant, the axial force F provided by the fastener 530 decreases. Furthermore, the clamping of the fastener 530 by the clamping wall 111 and the abutting portion 240 can limit the rotation of the fastener 530, thereby limiting excessive axial movement of the fastener 530 and further limiting the magnitude of the axial force provided by the fastener 530. Therefore, by setting the fastening structure 010, the force applied to the fixing frame 511 by the fastener 530 assembled on the fixing frame 511 can be reduced, the depth of the fastener 530 driving into the fixing frame 511 can be limited, and the problem of deformation and damage of the fixing frame can be effectively improved.

[0057] The included angle between the set direction a and the axial direction of the fastener 530 may be 90°, 88°, etc., which is not specifically limited here.

[0058] It should be noted that the fixing frame 511 may refer to a single structural bracket formed in one piece, or may be an assembled bracket composed of multiple separate parts assembled together, which is not specifically limited here.

[0059] Optionally, the fixing frame 511 is provided with a groove, and the fastening structure 010 is embedded in the groove to ensure reliability of the fastening structure 010 being assembled to the fixing frame 511 .

[0060] Of course, in other embodiments, the fastening structure 010 may also be assembled to the fixing frame 511 by bonding, clamping, etc., which is not specifically limited here.

[0061] Optionally, the fastener 530 may refer to a fastener 530 having an external thread on its surface, such as a bolt or a screw, and the above-mentioned fastener 530 is clamped between the clamping wall 111 and the supporting portion 240. It may mean that the clamping wall 111 and the supporting portion 240 are clamped on the external thread, or embedded in the gap between the external threads and clamp the fastener 530, etc., and no specific limitation is given here.

[0062] Alternatively, see Figure 2 and, Figure 3 、 Figure 4 and Figure 5The first fixing member 100 is provided with a first fastening hole 110, a portion of the hole wall of the first fastening hole 110 is a clamping wall 111, and the first fastening hole 110 and the second fastening hole 210 are used to set the fastener 530; both the first fastening hole 110 and the second fastening hole 210 are long holes; please refer to Figure 6 and Figure 7 When the first and second fixing members 100 and 200 are not subjected to external pressure, the hole formed by the overlapping projections of the first fastening hole 110 and the abutting portion 240 on the set plane b has a first aperture in the set direction a. When the first and second fixing members 100 and 200 approach each other under the pressure of the fastener 530, the first and second fixing members 100 and 200 move relative to each other along the set direction a, and the hole formed by the overlapping projections of the first fastening hole 110 and the abutting portion 240 on the set plane b has a second aperture in the set direction a. The first aperture is larger than the second aperture; the set plane b is parallel to or coincides with the set direction a. This arrangement allows the fastener 530 to be stably installed using the fastening structure 010.

[0063] Furthermore, the lengths of the first fastening hole 110 and the second fastening hole 210 both extend along the set direction a. This arrangement ensures that the first fixing member 100 and the second fixing member 200, which move relative to each other along the set direction a, can reliably clamp the fastener 530 between the hole wall (i.e., the clamping wall 111) of the first fastening hole 110 and the abutting portion 240.

[0064] Exemplarily, the first fastening hole 110 and the second fastening hole 210 are both waist-shaped holes, and the arc hole wall at one end of the length extension direction of the first fastening hole 110 is the clamping wall 111; when the first fixing member 100 and the second fixing member 200 are not squeezed by external force, the projections of the first fastening hole 110 and the supporting portion 240 on the set plane b completely overlap and form a hole with a length (first aperture) of 6.2 mm in the set direction a; when the first fixing member 100 and the second fixing member 200 approach each other under the squeezing of the fastener 530, the first fixing member 100 and the second fixing member 200 move relative to each other along the set direction a, and the projections of the first fastening hole 110 and the supporting portion 240 on the set plane b are misaligned and overlap to form a hole with a length (second aperture) less than or equal to 4 mm in the set direction a.

[0065] It should be understood that in other embodiments, the first fastening hole 110 and the second fastening hole 210 may also be rectangular long holes, which is not specifically limited here.

[0066] Of course, in other embodiments, the length extension direction of at least one of the first fastening hole 110 and the second fastening hole 210 forms an acute angle with the setting direction a.

[0067] Alternatively, in other embodiments, one of the first fastening hole 110 and the second fastening hole 210 is a long hole, and the other can also be a circular hole; or, both the first fastening hole 110 and the second fastening hole 210 are circular holes, and the hole diameter is larger than the outer diameter of the fastener 530.

[0068] Alternatively, in other embodiments, the first fixing member 100 is not provided with the first fastening hole 110 , and an arcuate concave surface is provided at one end of the first fixing member 100 not connected to the second fixing member 200 , and the arcuate concave surface is the clamping wall 111 .

[0069] Alternatively, see Figure 2 and Figure 5 The first fixing member 100 and the second fixing member 200 are elastically connected. This arrangement, through the elastic connection of the first fixing member 100 and the second fixing member 200, ensures that the fastener 530 disposed in the second fastening hole 210 is reliably clamped by the clamping wall 111 and the abutting portion 240, thereby ensuring the stability of the fastener 530 disposed in the fastening structure 010. Furthermore, after the fastener 530 is removed from the fastening structure 010, the first fixing member 100 and the second fixing member 200 are automatically reset under the action of the elastic force, thereby facilitating subsequent reuse.

[0070] Please refer to Figure 2 The second fixing member 200 of this embodiment includes a fixing portion 230 connected to the supporting portion 240, one end of the fixing portion 230 is connected to the first fixing member 100, and the other end of the fixing portion 230 is connected to one end of the supporting portion 240. The supporting portion 240 is located between the first fixing member 100 and the fixing portion 230, and the fixing portion 230 is provided with a second fastening hole 210; the other end of the supporting portion 240 can be supported by the fastener 530 passing through the second fastening hole 210.

[0071] It should be noted that the first fixing member 100 and the second fixing member 200 approach each other under the extrusion of the fastener 530, which may mean that when the fastener 530 is arranged in the first fastening hole 110 and the second fastening hole 210, and an extrusion force is applied to the first fixing member 100 along the axial direction of the fastener 530 itself, the first fixing member 100 moves toward the direction approaching the supporting portion 240 and the fixing portion 230, and at the same time, the supporting portion 240 also moves toward the direction approaching the fixing portion 230.

[0072] Optionally, in some embodiments, the fixing portions 230 of the first fixing member 100 and the second fixing member 200 can be configured to be distributed in parallel, which is conducive to reliably clamping the clamping wall 111 and the supporting portion 240 on both sides of the fastener 530, so as to further improve the stability of the fastener 530 assembled in the fastening structure 010.

[0073] Of course, in other embodiments, the fixing portions 230 of the first fixing member 100 and the second fixing member 200 may not be distributed in parallel, which is not specifically limited here.

[0074] Alternatively, see Figure 8 The angle α3 between the abutting portion 240 and the fixing portion 230 is 30°-60°, for example, 30°, 40°, 50°, 60°, etc., which is not specifically limited here. Setting the angle between the abutting portion 240 and the fixing portion 230 as an acute angle can further reduce the angle between the abutting portion 240 and the fixing portion 230 when the first fixing member 100 and the second fixing member 200 are squeezed by the fastener 530, ensuring that the first fixing member 100 and the second fixing member 200 can reliably approach each other and undergo relative displacement in the set direction a, so that the fastener 530 can be reliably clamped by the clamping wall 111 and the abutting portion 240.

[0075] Furthermore, the connection between the supporting portion 240 and the fixing portion 230 forms an arc transition. This arrangement ensures that the angle between the supporting portion 240 and the fixing portion 230 is smoothly reduced under the action of external force, thereby ensuring that the supporting portion 240 can reliably support the fastener 530, thereby improving the stability of the fastener 530 set on the fastening structure 010.

[0076] Further, please refer to Figure 2 The supporting portion 240 is provided with a notch 241, the notch 241 is used to accommodate the fastener 530, and the fastener 530 is supported at the notch 241 provided on the supporting portion 240. Such a setting can further improve the stability of the supporting portion 240 and the fastener 530.

[0077] The notch 241 may be arc-shaped, square-shaped, triangular-shaped, etc., which is not specifically limited here.

[0078] Of course, in other embodiments, the supporting portion 240 may not be provided with the notch 241 , and the end of the supporting portion 240 away from the fixing portion 230 is a supporting plane, which can be in contact with the fastener 530 .

[0079] The connection method between the supporting portion 240 and the fixing portion 230 includes but is not limited to integral molding and welding.

[0080] Please refer to Figure 2 and Figure 5The fastening structure 010 of this embodiment further includes a resisting member 400, one end of which is connected to the first fixing member 100, and the other end of which is capable of resisting the second fixing member 200. The provision of the resisting member 400 can improve the stability of the fastening structure 010. By utilizing the resisting member 400 and the second fixing member 200, the problem of excessive compression of the first fixing member 100 and the second fixing member 200 by the fastener 530 can be further improved, thereby alleviating deformation and damage of the fixing frame 511 caused by excessive axial pressure applied by the fastener 530.

[0081] Furthermore, the end of the abutting member 400 away from the first fixing member 100 can abut against the side of the abutting portion 240 facing the first fixing member 100. Of course, in other embodiments, the second fixing member 200 only includes the fixing portion 230, and the end of the abutting member 400 away from the first fixing member 100 can abut against the side of the fixing portion 230 facing the first fixing member 100.

[0082] Alternatively, see Figure 8 The included angle α4 between the abutting member 400 and the first fixing member 100 is greater than 0° and less than 180°; for example, 30°, 60°, 75°, 90°, 120°, 145°, 170°, etc., which are not specifically limited here. With this arrangement, when the first fixing member 100 drives the abutting member 400 toward the second fixing member 200, the abutting member 400 can reliably abut against the second fixing member 200, ensuring stability.

[0083] Of course, in other embodiments, the angle between the abutting member 400 and the first fixing member 100 can also be 180°. In this case, the abutting member 400 is equivalent to an extension of the end of the first fixing member 100 away from the second fixing member 200, and the end of the abutting member 400 away from the first fixing member 100 will not abut the second fixing member 200. Alternatively, in other embodiments, the angle between the abutting member 400 and the first fixing member 100 can also be 0°. In this case, the abutting member 400 is equivalent to overlapping with the first fixing member 100, and the abutting member 400 will not abut the second fixing member 200.

[0084] In other embodiments, please refer to Figure 9 The end of the abutting member 400 is provided with a bent portion 410, which can abut against the second fixing member 200. For example, the bent portion 410 is curved in an arc shape, and the convex surface of the curved portion 410 can abut against the abutting portion 240. The provision of the bent portion 410 can increase the contact area between the abutting member 400 and the abutting portion 240, thereby improving the stability of the abutment. It should be understood that the bent portion 410 is not required for the abutting member 400 and can be omitted as needed.

[0085] Please refer to Figure 2 and Figure 5 The fastening structure 010 of this embodiment further includes a connecting plate 300, through which the first fixing member 100 and the second fixing member 200 are elastically connected. Specifically, the fixing portions 230 of the first fixing member 100 and the second fixing member 200 are connected to the connecting plate 300 at an angle. When the first fixing member 100 and the second fixing member 200 approach each other under the pressure of the fastener 530, the angle between the connecting plate 300 and the first fixing member 100 and the angle between the connecting plate 300 and the fixing portion 230 of the second fixing member 200 both change, thereby ensuring that one of the first fixing member 100 and the second fixing member 200 can move relative to the other in a set direction a, so that the fastener 530 is clamped between the clamping wall 111 and the abutting portion 240. This arrangement ensures the stability of the fastener 530 when it is installed using the fastening structure 010.

[0086] It should be noted that the first fixing member 100 and the second fixing member 200 are elastically connected through the connecting plate 300, which specifically means that the portion at which the first fixing member 100 and the connecting plate 300 are connected at an angle is elastic, and the portion at which the fixing portion 230 of the second fixing member 200 and the connecting plate 300 are connected at an angle is elastic.

[0087] It should also be noted that the first fixing member 100, the second fixing member 200 and the connecting plate 300 can all be made of elastic metal or plastic, and the connection methods include but are not limited to one-piece molding, bonding, and welding, which are not specifically limited here.

[0088] It should be understood that in other embodiments, the first fixing member 100 and the second fixing member 200 may also be elastically connected by an elastic rubber block or the like, which is not specifically limited here.

[0089] Alternatively, see Figure 8 The angle α1 between the connecting plate 300 and the second fixing member 200 is 30°-80°. Specifically, the angle α1 between the connecting plate 300 and the fixing portion 230 of the second fixing member 200 is 30°-80°, for example: 30°, 40°, 50°, 60°, 80°, etc., which is not specifically limited here. The angle between the fixing portion 230 of the connecting plate 300 and the second fixing member 200 is set to an acute angle. When the first fixing member 100 and the second fixing member 200 are squeezed by the fastener 530, the angle between the fixing portion 230 of the connecting plate 300 and the second fixing member 200 changes (decreases) to ensure that the first fixing member 100 and the second fixing member 200 can reliably approach each other and undergo relative displacement in the set direction a, so as to reliably clamp the fastener 530 using the clamping wall 111 and the abutting portion 240.

[0090] Furthermore, the connection between the connecting plate 300 and the fixing portion 230 of the second fixing member 200 forms an arc transition. This arrangement ensures that the angle between the connecting plate 300 and the second fixing member 200 is smoothly reduced under the action of an external force. In other words, the spacing between the second fixing member 200 and the first fixing member 100 is reliably reduced, and the first fixing member 100 and the second fixing member 200 can smoothly adjust their relative positions in the set direction a, thereby ensuring that the fastener 530 is reliably clamped between the clamping wall 111 and the abutting portion 240.

[0091] Alternatively, see Figure 8 The included angle α2 between the connecting plate 300 and the first fixing member 100 is greater than or equal to 90° and less than 180°, for example, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 179°, etc., which are not specifically limited here. When the first fixing member 100 and the second fixing member 200 approach each other under the pressure of the fastener 530, the included angle between the connecting plate 300 and the first fixing member 100 increases to ensure that the first fixing member 100 can smoothly approach the second fixing member 200 and ensure that the first fixing member 100 and the second fixing member 200 can reliably move relative to each other along the set direction a, thereby reliably clamping the fastener 530 between the clamping wall 111 and the abutting portion 240.

[0092] Alternatively, see Figure 2 The connecting plate 300 is provided with a first weight-reducing opening 310. The provision of the first weight-reducing opening 310 can reduce the weight of the fastening structure 010 and can also reduce the input of raw materials for preparing the fastening structure 010, thereby reducing costs.

[0093] Furthermore, the second fixing member 200 is provided with a second weight-reducing opening 220, which is connected to the end of the first weight-reducing opening 310 away from the first fixing member 100. This configuration forms a hollow portion at the connection between the connecting plate 300 and the second fixing member 200, thereby ensuring that deformation between the connecting plate 300 and the second fixing member 200 can easily occur. When the first fixing member 100 and the second fixing member 200 are pressed closer to each other by the fastener 530, the connecting plate 300 can move more smoothly and reliably toward the direction approaching the second fixing member 200, thereby reliably reducing the angle between the connecting plate 300 and the second fixing member 200, thereby ensuring that the fastener 530 is reliably clamped by the clamping wall 111 and the abutting portion 240.

[0094] The process of assembling the fixing frame assembly 510 of this embodiment on the bottom box includes: placing the fixing frame 511 on the bottom box, inserting the fastener 530 into the first fastening hole 110 and the second fastening hole 210, rotating the fastener 530, and using the squeezing effect of the fastener 530 to move the first fixing member 100 toward the direction close to the second fixing member 200, and causing the first fixing member 100 and the second fixing member 200 to move relative to each other along the set direction a until the fastener 530 is clamped by the clamping wall 111 and the supporting portion 240, and the fastener 530 is connected to the bottom box.

[0095] In summary, the fastening structure 010 of the present invention can be set on the fixing frame 511 of the electrical device 020, so that the fastener 530 can be assembled on the fixing frame 511 through the fastening structure 010, thereby reducing the force applied to the fixing frame 511 by the fastener 530 assembled on the fixing frame 511, limiting the depth of the fastener 530 driven into the fixing frame 511, and effectively improving the problem of deformation and damage of the fixing frame 511.

[0096] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
